 It might be worth taking the door off if it's not really difficult. So you could take it and lean it against a sawhorse or something like that and just hose it off. You don't want to use a pressure washer, I don't think, because it'll blow everything out. So just hose it off. I would use like a 60-second cleaner or 30-second, I forget what it is, just a utility house cleaner, spray it on, and then hose it off.
